As an instrument for human communication, language is used in many w a y s not only with sounds by speaking but also with signs by picture or with written symbols by written. In order side, languages have self- expressions as actions via utterances. According to Clark, 1981:1 language is not only the principal medium that human beings use to communicate with each other but also to their culture. There are so many functions of language, some of them are to give information, deliver messages, express feelings, persuade people, entertain people, and share opinions. Considering those various functions of language mentioned above, in simple word we can conclude that language function as a tool of communication. Communication itself is the activity or process of expressing ideas and feeling or of giving information Hornby, 2000:225. It means when people use language, they need not only to interact with others but also to get other persons to understand their ideas and feeling. According to Halliday 1983 in his book “Explanations in the functions of language” a functional approach to language means, first of all, investigating how language is used: trying to find out what the purposes that language serves for us, and how people are able to achieve these purposes through speaking and listening, reading and writing. By looking at this sentence, the writer concludes that actually, language function here refers to the purpose itself. It means that by noting the function, it can lead people to understand the purpose conveyed by someone’s talking. For the example of the utterance “close the door” That sentence carries a function and the function reflects clear purpose of someone’s digilib.uinsby.ac.id digilib.uinsby.ac.id digilib.uinsby.ac.id digilib.uinsby.ac.id digilib.uinsby.ac.id digilib.uinsby.ac.id digilib.uinsby.ac.id utterance. The purpose of that function is asking the hearer to close the door after open it. Therefore, since language function refers to the purpose of utterance, the writer sees that language function is important in doing communication because it leads the hearer to achieve the purpose of someone’s utterances. However, in doing communication, the writer believes that people’s utterances with a purpose. The speaker has already defined the purpose of his or her utterance. When people speak to others with purpose, certainly the hearer might be able to get the message of the talking. Opposite, if the speaker’s utterances with no purpose, of course the hearer might get confused because the speaker does not know the point or the idea of his utterance. When normal people doing communication with others normal people, perhaps there is easily to understand what the purpose or message of their talking about. But how normal people doing communication with abnormal people, such as people who suffer mental disorder like schizophrenia disease. As we know that people who suffer schizophrenia usually they have a strange and beyond our understanding, including hallucinations and delusions that is hard to understand for normal people who doing communication with them. Schizophrenia is a mental disorder chronic and it can be make the brain useless.

Experiences like this is terrible and can cause fear, addiction or extreme anger. People with schizophrenia may speak unreasonable, can sit for hours without moving or much speak and also seems fine until they tell themselves what they actually think. According to Neil R. Carlson in his book Psychology of Behavior, the population of schizophrenia develops approximately one percent during human lifetime and more than two million Americans suffer from the illness in a given year p.578. Schizophrenia is a chronic and lifelong illness which needs certain treatments, therapies and medications. Half of the beds in America’s mental institutions are occupied by schizophrenic patients because many of them spend their entire adult lives hospitalized, with little hope of ever returning to a normal existence Zimbardo and Gerrig, 1996, p.656. This illness usually appears in the teenagers and it strikes without regarding the gender, race, social class or culture. Schizophrenia is rare among the children. Nearly one-third of people who is diagnosed with schizophrenia will try suicide and about ten percent of those with the diagnosis will commit suicide within twenty years of the beginning of the disorder Spearing, 2002, para.5.Patients with schizophrenia should be accompanied by people close to them, because people with schizophrenia need the spirit and support of the people around him to get rid of this mental illness.
